Product Description
General
Chenghe Oil Immersed Power Transformer Manufacturers includes hermetically sealed, amorphous alloy, conservator type and on-load tap changer type, which is usually pole mounted or installed in distribution station for daily lighting and factory power whose LV output up to 0.4kV. Our distribution transformer rating is up to 2500kVA, and primary voltage up to 35kV. The corrugated tanks as thermal expansion and contraction component enable the transformer oil completely isolated with the atmosphere. Oil distribution transformer with primary voltage range of 6,10,10.5,11,20,22,24,33, 35,38.5kV can be manufactured according to customer requirements.

Advantages
Our company in the traditional structure and mature technology based on a lot of improvements, such as the use of:
1.With longitudinal oil path spiral coil, interior cooling effect better;
2.Improved the effectual support of the loop's terminal face to strengthen the anti-short circuit electricity capability;
3.The new hoisting structure and body positioning structure are adopted to ensure more reliable in long distance transportation and operation;
4.We have many unique and reliable structures to serve you;
5.When you choose higher performance level transformers, you will enjoy greater technique intensity.
6.We Choose oxygen free copper wires with lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of
our transformer is lower and the electric performance is better.
7.We use high quality silicon steel sheet,with the improvement of performance level, use lower unit loss of silicon steel sheet , so that the transformer no-load loss is
lower.
8.We use high-quality laminate insulation, no cracking, even under the effect of short circuit current. wensibudong.
9.We use deep filtered transformer oil, lower water content, gas content, impurity levels, transformer work more reliable.
10.We use high quality rubber sealing materia, which can prevent the transformers from aging or leakage.
11.All raw materials through the quality inspection, and all the raw materials factories has pass through the national standard ISO9000 inspection.
